I've do hand quilting for me, and would LOVE to do it for others....but have not had the opportunity. I would think that it would depend on how small the stitches are, how intricate the pattern,etc. Take a look at what is already done on the quilt that you have to match. Are the stitches teeny, tiny or regular type? Is there a lot of area that needs to be covered w/quilting and is it a curved, more complicted pattern? or just basic? these are things that you would need to consider because it was mean more time or less time involved. Also, do have have to bind the quilt when you are finished? this is extra.
Have fun! XO
